Applicationfiled December :25, 1911. Serial No. 688,564.

T 0 all whom it may concern Be it known that I, ALBERT Kinsman LOVELL, a citizen of the United States of America, and resident of New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Roller W indow-Screens, of which the following is a specification.

My invention relates to window screens,

and it has for its object to provide a roller window screen which shall automatically cooperate with the window sash to screen the opening in proportion as the sash is raised, leaving the glass at all times unobstructed, and which shall be adapted for instantaneous removal from the sash and frame by simple liberating movement of the engaging devices by which it is held to said parts.

' To this end the invention consists in the novel combination, arrangement and construction of parts as hereinafter more fully described and claimed.

In the accompanying drawings forming a part of this specification, Figure l is a perspective "iew of my improved roller screen, shown in its application to a window frame and the lower window sash, which is represented in the raised position and with the flexible screen unwound. Fig". 2 is a horizontal cross section through the edge of the screen and the guide ways on the plane of one oi the screen retaining pinions journaled within the guide ways. tive view of an end of the stationary housing inclosing the screen rolling apparatus, showing the means for holding the spring supporting core against rotation. Fig. 4 is a vertical cross section through the screen, its housing and screen rolling apparatus, showing the guide ways in elevation, in the direction of the axis of the screen rolling apparatus. I ig. is a vertical longitudinal section through the screen rolling apparatus on the axial line and plane of the screen. Fig. (i is a vertical longitudinal section in the plane of the screen through the screen holding and fastening devices for securing the non rolling end of the screen to the Window sash. Fig. 7 is a vertical cross section through the same on the line 7, 7, of Fig. 6. Fig. 8 is a horizontal cross section similar to Fig. 2 of a modification of the screen, and

Fig. 8 is a perspec-- upper sash to screen the upper half of the opening, and that the construct-ion in the two cases will difi'er only in inversion, either being susceptible of employment alone, or

used together, as desired. Only a single edge of the screen is shown, which will suffice to illustrate the construction, as both edges are operated alike. Similary, only a single side of the window is shown, namely, the right hand side viewed tronrthe interior of the room in which it is placed. The view embodies the right hand end of the cap stool A, or lower horizontal part of the window trimming, the vertical right hand casing B, and the vertical stop I) secured in a plane at a right angle to the casing and forming one side of the usual groove in which the lower sash E .is adapted to travel. These parts of the window architecture are common, and well known and need not'be'further shown or described.

The invention contemplates the use of a flexible screen 1 attached at its respective ends to the window sash and to a roller mounted on the casing with each side edge of the screen received and adapted to travel in a guideway attached to the vertical stop l). Said guideway comprises a pair of vertical guide strips 9, 2 each formed wit-h a flange by which it is separately attached to the stop by the screws 3, and a part -1- parallel therewith but oil-set from it a certain distance. The onset parts of the re spective guide strips forming a pair are projected toward each other and set at the proper distance apart to provide a slot 5 ctween their edges, which slot forms the guidcway for the reception and movement of the edge of the screen, as fully shown in Figs. 2 and l. Thetwo strips forming a guide way may be adjustml when placed upon the casing to fit various thickness of screen as required.

A plain strip i is riveiioii to the wriiczii-iimh of the migg'io )hiie on the oiiiei' side of the screen, with he Pivot in passing through ihe screen, as

iown in Fig. .i. The onii of i our 28 are iti'erl to iiiigiwi: and s Hie in ii siiiicio Way jourmiiod upon miiiuhio pivots 34: upon which they are zuhipijwi to revolve. The pinions are so positionwi ihal; their teeth ongmgo iho edges' of :he SL'0Qfi.,, passing 5 through i'ho meshes thereof, and their purpose is to hohi ihe SPIEGD ciiswicndmi infer- :illy and provcnt its edges from Wii'hd ':1W i ing from. the guide slot it travels therein. i 8 and 9 show modificuiion in which a iis flexible band 7' is sewed to the edge of the screen by the thread t, and the band is provided with a series of perforations w for engaging the teeth of the pinions. In such modifications the bar it at the upper end of the screen will differ from the bar 28 only in stopping at the inner edge of the band, as shown in said F gurus.

In the operation of my improved roller screen, it will be understood that with the guide strips and sockets of the rolling apparatus secured to the window casing, and the sockets opened as shown by the dotted lines in Fig. 4:; it will be necessary, in assembling the other parts of the screen rolling apparatus, to first wind the screen on the drum 21 by hand, without disturbing the spring 520, that is, leaving it in its normal state of repose, and without tension. The drum with the screen so wound entirely upon it may then be inserted in the housing 22, after the removal of one of the cross bridges 2st therein, the end of the screen adjacent the bar 28 atthe same tilne being slid along the slot 23 ot' the housing, with. the bar on the outside of the housing. When the drum and screen are entirely inserted to place in the housing all said parts may be seated in the half bearings 6 and the other half bearings 8 may then be closed upon the parts and locked in such position by the en gagement of the latches 13 with the catches 17 on the respective half bearings. In such position thesmall bearings at the centers of the half disks will form whole bearings which receive and support the projecting ends of the rod 19, and the flange of the sockets will retain the housing in place. Thus either of these features will alone support the screen rolling apparatus, but both may contribute in such function. The flanges however are required for the purpose of covering the ends of the housing and providing tight joints at those places.

\Yith the parts of the screen rolling ap paratus in place, and the bar 28 lying over and along the longitudinal slot. 23 of the housing, if the window sash be moved to its lowest position or seat, the eyelets 29 of the bar will enter and project through the perforations 27 of the bracket plate, 26, and also the slots 31 of the locking strip 30, provided the strip is placed at the proper end of its throw, to bring the clearance space of the slots at the ends of the key tongues 32 provided for that purpose in alinement with the cvclcts. A slight longitudinal motion of the locking strip will then engage the key tongues with the eyelets and the screen will then 'be fastened to the window sash in readiness for use. Then as the sash in operation is raised the screen will be unrolled from the drum and follow it upward. to screen the opening in the window, and the spring will be correspondingly coiled into tension upon its supporting rod. With the spring in a state of tension it will conversely revolve the drum and automatically wind the screen upon it as the window sash is lowered, thus always maintaining the screen straight and distended over the varying width of the window opening. In this movement the edge of the screen will ride upon and in engagement with the teeth of the pinions 33, thus preventing the flapping of the screen at its edges and theindisengagement from the guide way of the guide strips. The window light always remains unobstructed by the screen, and when it is desired to open the window without the opening being covered by the screen, it is only necessary to disengage the key tongues of the locking strip from the eyelets of the screen by the reverse movement of the strip from that used in looking the parts, when the sash is at its lowest position and the screen is withdrawn into the housing.
